SPECIFICATION. formingpart of Letters Patent No. 237,029, dated January 25, 1881.

- Application filed October 21, 1880. (No model.)

To all whom it may concern:

Be it known th3th,I, WILLIAM S. LANEY, a citizen of the UnitedStates, residing at Lithopolis, in the county of Fairfield and State of Ohio, have invented certain new and useful Improvements in Pumps; and Idohereby declare the followiugto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, andto letters or figures of reference marked there on, which form a part of this specification.

This invention relates to improvements in that class of pumps in which a hollow pistonrod is used and the water is forced up through the piston and rod by the working of the latter. It consists in the construction and arrangement of the several parts hereinafter explained and claimed.

In the drawings, Figure 1 is a front elevation. Fig. 2 is a side elevation, and Figs. 3, 4, and 5 are detail views of a pump constructed according to'my invention.

I employa substantial frame, A, in which is supported the mechanism of my invention. This frame is composed of a base, a, vertical rods a. a, and platform a all firmly secured together, and so formed and arranged that the base can be let down into the water and the platform be supported at the top of the well or reservoir.

In the base a valve-chambers a are formed and communicate with the open lower ends of the cylinders 12 b, which are firmly secured in their vertical positions on the top of the base. The valve-chambers are formed from the side of the base, and in them are inserted the checkvalves a, which may be easily removed for any desired purpose.

a is a support for the operator when he is pumping water.

Within the cylinders b the lower ends of the hollow piston-rods 0 o are placed, and to which are fixed the pistons 0 The pistons work snugly'in the cylinders, and are provided with suitable check-valves in their lower ends. The upper ends of thepistOn-rods pass through the platform a and have fixed thereon foot-rests a, so that they: can be operated'by the feet.

0 c are handles which extend upward from the foot-rests. They are arranged so that they can be taken hold of by the hands, and afford facilities whereby the muscular effort of the arms can be brought into simultaneous action with the alternate treading by the feet on the foot-rests.

The removable top 0 of piston-rod c is carried upward above the foot -'rest, and is so formed as to serve as a discharge-pipe. The

upper end of the piston c is closed, preferably by a removable plug, 0 so that, when desired, water may be discharged from both pistonrods, or so that the stem 0 and plug 0 may be substituted one for the other and the flow of water all directed through piston-rod a.

dis a hollow standard placed between the cylinders 12, closed at its upper end and having its lower end open and fixed to the base a, and connected by tubular ways d (indicated in dotted lines, Fig. 1) with the valve-chambers 0.

On the upper end of the standard d is the oscillating beam d ,.to the ends of which are fixed one end of the connecting chains or links (F, the opposite ends of which are fixed on pins d on the sides of the piston-rods 00. By this method of connection the piston-rods have a vertical reciprocating movement when the pump is operated. The piston-rods, near their upper ends and just below the platform, are connected by a pipe, 0, which permits the water to flow from one into the other. This pipe 6 may be made of flexible material, or it may be a stiff metallic pipe. If made of metal, its ends must be connected by a packed joint to the pistons, so that it will turn readily and adjust itself to the reciprocating movement. If made of rubber or other flexible piping, it will bend sufficiently to adjust itself to the reciprocating movement.

The operation of the device is readily comprehended. One of the pipes, cor c, is closed at its top by the plug 0 The operator places his feet on the rests c and by changing his weight from one to the other causes the pistonrods to work reciprocally and thereby raise the water. The water from the piston-rod c flows through the pipe e into piston-rod c, from which there will be a steady continuous flow.

Having thus described my invention, what Iclaim, and desire to secure by Letters Patent, 1s

1. The combination, with the hollow reciprocating piston-rods, of a cross pipe or tube connected to both piston-rods and having a reciprocating movement therewith, substantially as set forth.

2. In a pump having hollow reciprocating piston-rods, the foot-rests 0 0 near to the top thereof, and the vertical hand-rods 0, having theirlower ends fixed to the foot-rests, substantially as and for the purpose set forth.

3. In a compound pump, two hollow pistonrods connected together by and balanced upon I the ends of a rocking bar pivoted to a fixed standard arranged between them, and having on their upper ends foot-rests, whereby they I may be operated by an alternate treading l movement, substantially as set forth.

4. In a double hollow piston-rod pump, the frame A, composed of a base having horizontal valve-chambers formed therein, two vertical cylinders fixed on the top of the base and communicating with the inner ends of the valve-chambers, a vertical standard placed between the cylinders and having its lower end tixed to the base and its upper end extended above the plane of the upper ends of the cylinders, a rocking bar pivoted on the upper end of the standard, a series of vertical side rods having their lower ends fixed to the base and their upper ends extended upward to the platform, and a platform fixed on the upper ends of the side rods, all arranged and adapted to carry the reciprocating hollow piston-rods and pistons and valves, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
